BACKGROUND/AIM: The mandibular angle fracture is a challenging fracture to manage. Over time, the literature has shown many types of treatment modalities and different kinds of internal fixation. The aim of this study was to evaluate the outcomes and complications of mandibular angle fractures managed by Champy's technique and two-plate fixation, over a period of 20 years. MATERIAL AND METHODS: The files of 149 patients with 155 angle fractures fulfilled the inclusion criteria and were chosen for this study...

Computer-assisted surgical (CAS) planning tools are available for craniofacial surgery, but are usually based on computer-aided design (CAD) tools that lack the ability to detect the collision of virtual objects (i.e., fractured bone segments). We developed a CAS system featuring a sense of touch (haptic) that enables surgeons to physically interact with individual, patient-specific anatomy and immerse in a three-dimensional virtual environment. In this study, we evaluated initial user experience with our novel system compared to an existing CAD system...

PURPOSE: During surgery for major maxillofacial fractures, orotracheal intubation can interfere with some surgical procedures and nasal intubation can be contraindicated or impossible. That is why tracheotomy is presented as a solution, although it carries a relatively high incidence of complications. In this study, the use of submandibular tracheal intubation is basically evaluated as an alternative to tracheotomy in such circumstances. MATERIALS AND METHODS: This prospective study was performed in patients undergoing surgery for major maxillofacial fractures in which oral intubation and/or nasal intubation have been unsuitable, impossible, or contraindicated...

BACKGROUND: Trauma is a leading cause of injury and mortality and may involve mandibular fractures and cervical spine injuries. Manipulation of the spine during trauma protocols and operative treatment has the potential to cause serious spinal cord injuries. The purpose of this study was to identify risk factors associated with cervical spine injury (CSI) in patients with mandibular fractures. METHODS: The National Trauma Databank (2007-2010) was used to identify patients with mandibular fractures...

PURPOSE: To compare the clinical effects of mandibular angle fracture surgery through intraoral and extraoral approach. METHODS: From January 2008 to December 2014, 46 patients with mandibular angle fracture were retrospectively recruited in this study. An intraoral approach was used in 22 cases as group 1 in whom the fractures were fixed by one titanium miniplate alone, the others through an extraoral approach as group 2 in whom the fractures were fixed by two plates...

BACKGROUND: Primary hyperparathyroidism is caused by the excessive growth of parathormone secretion, its consequence being hypercalcemia. The parathyroid adenoma is responsible for over half of primary hyperparathyroidism cases. The mandibular tumor can be the initial sign in the case of primary hyperparathyroidism. CASE PRESENTATION: We present the case of a 33 year old patient with history of a mandibular operated tumor, repetitive pathological fractures and hypercalcemia manifestations...

OBJECTIVES: We evaluated and recorded post-traumatic and postoperative neurosensory deficits of the inferior alveolar nerve (IAN) in mandibular fracture in order to identify associated risk factors. MATERIALS AND METHODS: This was a prospective cohort study composed of 60 patients treated for mandibular fracture. The primary study variable was the change between the post-traumatic IAN neurosensory examination score and the score after fracture reduction. Risk factors were categorized as demographic, anatomic, fracture displacement, and treatment...

INTRODUCTION: The aim of this in vitro study was to evaluate the effects on root dentin of 2 trephining techniques using an ultrasonic tip or a trepan bur in the mesial canals of mandibular molars during attempts to remove fractured file fragments using micro-computed tomographic imaging. METHODS: Twenty-one teeth with a similar anatomic configuration in mesial (buccal and lingual) canals were selected. A 4-mm apical segment of K3 file size 25/.06 was fractured in each mesiobuccal and mesiolingual canal 5 mm apically from the canal orifice...

PURPOSE: The aim of this follow-up study was to report the long-term outcome of all-ceramic cantilever resin-bonded fixed dental prostheses (RBFDPs). MATERIALS AND METHODS: In 16 patients (mean age of 33.3±17.5years) 22 RBFDPs made from a glass-infiltrated alumina ceramic (In-Ceram) were inserted with a phosphate monomer containing luting agent after air-abrasion of the retainer wings. The abutment preparation included a shallow groove on the cingulum and a small proximal box...

BACKGROUND: Previous studies focused on the dental caries status of East African children and not on their overall dental needs. Urban children consume more sugar-rich foods. OBJECTIVES: To assess overall dental treatment needs of children living in an orphanage in Uganda. STUDY DESIGN: Teeth were diagnosed as needing treatment by obvious frank carious lesions (WHO criteria), temporary fillings, staining, or very deep pit and/or fissures possibly requiring sealants...

BACKGROUND: The effectiveness of bicycle safety helmets in preventing head injuries is well- documented. Recent studies differ regarding the effectiveness of bicycle helmets in preventing facial injuries, especially those of the mid-face and the mandible. OBJECTIVES: The present study was conducted to determine the protective effect of a bicycle helmet in preventing mid-face and mandibular fractures. PATIENTS AND METHODS: Data from an accident research unit were analyzed to collect technical collision details (relative collision speed, type of collision, collision partner, and use of a helmet) and clinical data (type of fracture)...

Exact localization of foreign body is important for planning the treatment required for its retrieval without much tissue damage. Plain film radiography is the initial screening modality used for the detection of suspected foreign body. However, about one-third of all the foreign bodies are missed in the initial radiographic examination. In case of a wooden foreign body, only 15% are well-visualized on plain radiographs and are, therefore, often missed or misdiagnosed. Hence, the different radiographic technique should be used to localize the object instead of relying on a single radiographic image...

The purpose of this study was to compare the mechanical resistance of three different plates used to treat fractures of the mandibular angle: a regular 4-hole plate, a longer 4-hole plate (both positioned using the Champy technique), and a 3-dimensional plate positioned over the oblique line. Three equal groups of replicas of human dentate mandibles made out of polyurethane resin were used (n=21 in each group). The force was applied perpendicular to the occlusal plane at a rate of 2mm/minute at three different points: the first molar on the sectioned side; the first molar on the contralateral side; and between the central incisors...

OBJECTIVES: The objectives of this study were to study and investigate the relation between the state of the lower last molar teeth eruption and the site of the mandibular fractures. METHODS: Adult patients with traumatic mandibular fractures were included in this study. Panorama and computed tomography was performed for all patients. The relation between the state of the lower last molar eruption and criteria of the fracture was analyzed. RESULTS: In 106 patients who had 168 mandibular fractures, impacted lower third molar teeth were found to significantly increase the incidence of mandibular angle fracture while they had nonsignificant effect on incidence of other sites of mandibular fractures...
